Sunlight

It's a sad fact that many sea turtles now suffer from fibropapillomatosis, a disease in which tumors grow on various parts of the body. There may be new hope, however, as a study suggests that sunlight exposure could help afflicted turtles recover.

There are many parts of the world in which fresh water may be plentiful, but it's also full of harmful microbes. An experimental new filter is able to purify such water for drinking, and it's powered solely by sunlight.

It's possible that someday in the future, sunlight-powered robots may be able to swim across marine oil spills, soaking up the oil as they go. A tiny prototype has already been created, and it was inspired by both the steam engine and an insect.

As sunlight passes through a building's windows it can cause indoor temperatures to rise, to the point that the structure's air conditioning system has to be used. A new window material, however, blocks incoming heat while staying mostly transparent.

Virtually any camper will provide a tabletop on which to plant a laptop, but Sunlight takes the mobile office a step further, demonstrating how a dining table-cum-desk can support everything from basic office work to scientific fieldwork.
-
Ironically, many of the places that most require water purification have the least-developed infrastructure. That's where a new filtration device comes in, as it's activated by the sun – and it works relatively quickly.
-
If you worked in a dingy, windowless environment, it would be nice (and energy-efficient) if you could get natural daylight "piped in" from outside. An experimental device does exactly that, in a new compact and robust form.
-
Researchers have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the ambient temperature. Painted on a building, the new paint could help cut cooling costs and energy use.

Even though we're warned about the harmful effects of ultraviolet (UV) rays in sunlight, they're essential for the production of vitamin D in the body. Now, scientists are claiming that UV LEDs could serve as a safe alternative to sunlight.
-
By converting liquid salt water – or tainted water – into steam, it's possible to obtain pure, clean drinking water. Doing so could soon be cheaper and easier than ever, thanks to a newly developed material.
-
New research has for the first time demonstrated how exposure to Narrow Band Ultraviolet B light (UVB) can directly influence gut microbiome diversity in humans. The research hypothesizes this result is modulated by vitamin D.

ScienceBack in 2014, MIT scientists developed a graphite/carbon "sponge" which used sunlight to convert water into steam. They've now improved on the design, creating a device that produces super-heated steam. It could be used in remote regions to sterilize medical equipment, among other applications.
